And of these things, as we have said already, one might take account in the case of a man who held Catholic sentiments and belonged to our own number; but as to one who has betrayed the mystery (of the faith), and who swaggers with the abominable heresy of Artemas,— for why should we hesitate to disclose his father?— we consider it unnecessary to exact of him an account for these things.
